#3 COAT WITH OIL

Apply a thin layer of cooking oil or grease to the clean cookware, including the bottom and handle. The best type of coating is widely disputed, but canola oil, flaxseed oil and shortening all work. Go with your favourite, or whatever’s on hand. For the pan pictured above, I applied canola and rendered bacon fat. Using a clean cloth or clean fingers, work the coating into every nook and cranny of the cookware, then wipe off any noticeable excess with paper towel.
